Formula
Formula
g/s = lb/day × 0.005249912
Multiply any value in pounds per day by 0.005249912 to obtain the value in grams per second.
Worked example
Convert 1000 lb/day to g/s.
- 01Start with 1000 lb/day.
- 02Multiply by the conversion factor: 1000 × 0.005249912 = 5.24991 g/s.
Result1000 lb/day = 5.24991 g/s

FAQ
What is the conversion factor from lb/day to g/s?
1 lb/day equals 0.005249912 g/s. To convert, multiply the value in pounds per day by 0.005249912.
How do I convert 1 lb/day to g/s?
1 lb/day = 0.00524991 g/s. For any value, multiply by 0.005249912.
How do I convert g/s back to lb/day?
Divide by the same factor — or equivalently, multiply by 190.4794. So 1 g/s = 190.479 lb/day.
When would I need to convert pound per day to gram per second?
Mass flow conversions between lb/day and g/s are common in material balances, process stream summaries, bulk solids handling, custody transfer, and equipment sizing where kg/hr, t/hr, lb/hr, and lb/s may all appear in different datasheets or vendor documents.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
